DAY 1: Wednesday 1st December, 2021

Session 1 - Agroecological crop and livestock protection (Axe 2)

>> Mathilde DIONISI -Modeling multiple pests in rice crops for agroecological rice protection in Cambodia

2021-2024, SEVAB (France)
Supervisors: Jean-Noël Aubertot (INRAE), Mathilde Sester (CIRAD)
Funding: CIRAD-INRAE, WAT4CAM project and CRP RICE
Location: Battambang Province, Cambodia
Objective: Rice is the most important agricultural production in Cambodia. Farmers grow rice for food and income. Rice crops receive enormous amounts of pesticides, Flor et al., 2019). Farmers often mix several pesticide products and spray preventive treatments. A better characterization of the main drivers of biotic stresses will permit to limit useless pesticide treatments in rice crops and to adapt cropping practices to production situations, especially to the local biodiversity.

2018-2021, Montpellier University (France)
Supervisors: Stéphane Bellafiore (IRD), Lionel Moulin (IRD)
Location: Stung Chinit, Kampong Thom Province, Cambodia
Objective: test the potential of conservation agriculture to reduce the abundance of plant parasitic nematode by understanding the soil food web and measuring the effects of conservation agriculture or conventional tillage and 4 rice varieties on the communities of microorganisms (bacteria, fungi and nematodes)

>> LENG Vira - Assessing the impacts of conventional plough-based management and no-till cropping systems on soil organic C dynamics and greenhouse gas emissions in the uplands of Cambodia 

2021-2024, Institut Agro, Montpellier University (France)
Supervisors: Dr. Laurent Thuriès (CIRAD), Dr. Rémi CARDINAEL (CIRAD), SENG Vang (DALRM/GDA), Dr. Lyda HOK (RUA/CE SAIN), Dr. Florent TIVET (CIRAD) and Dr. Pascal LIENHARD (CIRAD)
Funding: ASSET project – FFEM component
Location: Cambodia, Bos Khnor research station
Objective: Assess the mitigation potential of Conservation Agriculture compared to conventional plough-based cropping systems on red Oxisols in Cambodia. The study is complementary of the study on LULCC with the objectives to highlight Soil Organic Carbon restoration potential and Greenhouse gas mitigation under no-till cropping systems when compared with conventional management.

DAY 2: Thursday 2nd December, 2021 

Session 3 - Design and assess innovative cropping & farming systems (Axe 3)

>> Thuan SARZYNSKI - Evaluation of new F1 hybrids of Coffea arabica selected for agroforestry systems in the context of climate change in the North-West of Vietnam

2020-2023, Institut Agro, Montpellier University (France)
Supervisors: Hervé Etienne (CIRAD), Pierre Marraccini (CIRAD), Philippe Vaast (CIRAD)
Funding: BREEDCAFS project, CIRAD and ECOM
Location: Son La and Dien Bien Provinces, Vietnam
Objective: Test the new hybrids in a multilocation trial set in the North-West of Vietnam and carry out the physiological and genetic analyzes in a research trial planted at NOMAFSI station (Son La province) with several hybrids together with local Arabica varieties under three contrasted water treatments (rainfed, water supressed, and irrigated).

Funding: Deakin University, Alliance of Bioversity-CIAT, Asia Hub, CMBP
Location: Thai Nguyen Province, Vietnam
Objective: Provide an overview of tea production in Vietnam, the challenges of conventional tea farming and potential benefits of agroecological tea management approach; assess and compare taxonomy and diversity of total bacterial and fungi communities in both conventional and agroecological tea management system; examine the colonization and diversity of AMF in association with tea plant chrono sequence; find out solutions to improve the soil health of agroecological tea management by assessing the impact of lime application as a case study.
